Illuminated sign display assembly

Abstract

The invention discloses an illuminated sign display assembly including a transparent substrate, a multilayer circuit structure, a light reflecting casing, and at least one light emitting unit. The multilayer circuit structure is disposed on the transparent substrate, and a hollow portion is formed on the multilayer circuit structure. The light reflecting casing is fixed on the transparent substrate by a welding process and covers the hollow portion of the multilayer circuit structure. The light emitting unit is disposed on the transparent substrate and located in the light reflecting casing. The light reflecting unit is electrically connected to the multilayer circuit structure. Once the multilayer circuit structure is powered on, the light emitted by the light emitting unit will be reflected by the light reflecting casing and then passes through the hollow portion of the multilayer circuit structure and the transparent substrate, so as to form an illuminated sign.
